interior of the nostrils whereby the device will be selfretaining.

The. guard isv preferably formed from a light and nonabsorbent material such as hard rubber, and its color is preferably pink, or nearly flesh colored, so as not. to detract the gaze of the wearerfrom his work.

As clearly shown in Fig. 1, the breath of the dentist, or. operator, is discharged through the flared open end 2 of the guard and directed to the side and behind the patient, while the dentist is working upon the right, hand( side of the patient. If the dentist wishes to work upon the opposite side of the patient, he.s'imply reverses the position of the guard so that his breath is directed 'to the left hand and behind the.

patient. I p

If desired, a suitable strainer carried by a ring 5 may be inserted within the flared 'end of the body 1 so as to protect the dentist against particles liberated by his drill 1 or the like. Further, if desired, a suitable packing 6 maybe placed within the bulged portionsof the extensions 3 and are pre ably of absorbent. material whereby they may be impregnated with asuitable medicine or purifier. 1

What I claim is: A-reversiblebreath guard .consisting of a hollow cylindrical body having aflared open end and a closed end, hollow nostril engaging extensions projecting laterally from the body at and adjacent the closed end thereof and communicating therewith.
